Solar Power System Composition

Solar energy is a renewable energy source. It refers to the thermal radiation energy of the sun, which is mainly represented by the sun's rays. Solar energy has the advantages of non-polluting, sustainable, large total volume, and wide distribution. In the environment of energy transformation and upgrading, it is quite popular.


I. Know the solar power system


The power generation principle of the solar power system is what we call a chemical reaction, that is, the conversion of solar energy into electrical energy. This conversion process is the process by which solar radiation energy photons are converted into electrical energy through semiconductor materials, usually called the "photovoltaic effect", and solar cells are made using this effect. You could get high quality solar power system from Anern solar supply store.


II. The composition of the solar power system


The solar power system is composed of solar battery packs, solar controllers, and storage batteries (groups). If the output power is AC 220V or 110V, an inverter is also required. The role of each part is:


1. Solar panel: high output solar panel is the core part of the solar power system, and it is also the most valuable part of the solar power system. Its function is to convert the sun's radiation capacity into electric energy, or send it to the storage battery for storage, or drive the load to work. The quality and cost of solar panels will directly determine the quality and cost of the entire system.


2. Solar controller: The function of the solar controller is to control the working state of the entire solar power system, and to protect the battery from overcharge and overdischarge. In places with large temperature differences, a qualified controller should also have the function of temperature compensation. Other additional functions such as light control switch and time control switch should be optional options of the controller.


3. Batteries: They generally are lead-acid batteries, nickel-metal hydride batteries, nickel-cadmium batteries or lithium batteries which can also be used in small and micro systems. Its function is to store the electric energy generated by the solar panel when there is light, and then release it when needed.


4. Inverter: In many occasions, 220VAC, 110VAC AC power supply is required. Because the direct output of solar energy is generally 12VDC, 24VDC, 48VDC. In order to provide electrical energy to 220VAC electrical appliances, the DC power generated by the solar power system needs to be converted into AC power, so a DC-AC inverter is required. In some occasions, when multiple voltage loads are required, a DC-DC inverter is also used, such as converting 24VDC electric energy into 5VDC electric energy (note that it is not a simple step-down).
